APPARATUS FOR CONDENSING STEAM.

SPECIFICATION forming part of Letters'Pa/cent No. 259,029, dated. June6, 1882, Application filed Septemherfli), 1881. (No model.) Patented inEngland January 28, 1880, No. 374.

To all whom it may concern:

Be it known that 1, ROBERT MUDGE MAR- CHANT, a citizen of Great Britain,residing at Saint Johns Square Passage, Olerkenwell, in

* the county of Middlesex and Kingdom of England, have invented certainnew and useful Improvements in Apparatus for Condensing Steam or otherVapors; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the letters or figures ofreference marked thereon, which form apart of this specification.

My invention relates to apparatus for condensing steam or other vaporsby means of cold water or air admitted to the condenser,

so as to act upon the steam or vapor by surface-condensation; and thesaid invention consists in the construction and combination of partshereinafter set forth and claimed.

The accompanying drawings represent a condenser constructed according tomy invention.

Figure l is a front elevation of the condenscr-case with the cover off,showing the condensing-compartments'with the front castiron 30. platefor these in position in the case. Fig. 2 is a sectional plan with thefront cover on the condenser-case, and showing thecondensing-compart'ments and front and back castiron plates in position,and the front ends of 3 5 the slotted pipes connected with the upperrectangular box-connector, into which is received the exhaust steam orvapor through the gauze protector. Fig. 3 is a front elevation of thecondenser-case with the cover off, and with 40 the front cast-iron plateprotector removed, so

that the exterior cups of the front condensingcompartment are seen. Fig.4 is a front elevation of the condenser-case with the cover on, and withthe rectangularbox-connectors in po- 44,5 sition, and provided with theattachments necessary for a water-condensing medium and for the supplyof both steam and water for the circulation of these to the boiler,where steam-pumps are used which pump both steam and water. Fig. 5 is aplan of the condenser, 0 showing the connections necessary for both awater and an air condensing medium, those for the air being shown indotted lines. Fig. 6 is a side elevation of the condenser-case, showingthe connections for water as acondensing medium. Fig. 7 represents insection the method of connecting the condensin g-com partments with theslotted pipes. Fig.8 represents a side elevation, where air is used asthe condensing medium; and Fig.9 represents a plan '60 view ofthe top ofthe compartments.

1n the above figures, a. is the condensencase; a, the rectangularbox-connectors; a a valve through which thecondensed steam issucked,where steam-pumps are used to pump both steam and water; I), thecondensing-compartments; 1), the slotted pipes; 11 the cups forming thedistance-pieces in support; 0, the castiron plates exterior to thecondensing-compartments, and holding any required number 7c of thesetogether. 0 is a circular plate suspended below the center of thewire-gauze c and acting as a shield or splash-board to receive anddistribute the exhaust-steam or other vapor, its object being to receiveany occasional particles of grease and keep these from collecting in thecenter of the wire-gauze. c are pipes conveying water to the condenserasits condensing medium. (1 is a pipe conveying the heated water fromthecondenser. d v

Each of my plates 0 is perforated with two or four holes for thereception of the connections of the pipes hereinbeforc referred to,these holes being near the top and bottom of 5 each plate, each hole atthe top being preferably opposite one at the bottom. The cups 1) formedon said plates keep them at the proper distance from each other. Theedge of each hole for a pipe-connection is raised so as to [0 form a rimequal to the depth of these cups,

and every alternate plate has a slightly larger hole,with an externaltaper to such raised edge, for the purpose of receiving the untaperededge of the hole of the adjoining plate. 1 construct is the indentationsor cups b so that when the plates are fitted together in pairs theseindentations or cups determine the distance between the two sides of thecompartment formed by each pair of the plates, and in such manner thatthe indentations or cups which determine the distance between thecompartments are clear of and at equal distance from and alternate withthe indentations and cups which separate the plates of each compartment.The depth of such indentations or cuppings determines the distancebetween the sides of each compartment, and also the distance between-Rthe compartments when fixed, as hereinafter explained. To efiect suchan arrangement, one-halt the number of the plates areindented or cuppedto a templet giving one position to the indentations or cups, and theother half are worked from another templet, giving to these indentationsor cups an intermediate position. This can be easily effected with apress-tool. The plates thus prepared are then securely fastened togetherat the edges and in pairs, so that each pair shall become a water or airtight compartment, capable of being connected at the holes beforedescribed with any number of similar water or air tight compartments. Iprefer to fasten the edges of the plates by lapping these edges over, sothat the exterior edge of the compartment is formed of fourthicknessesof plate, and the corners by the laps over are formed with eightthicknesses of plate. For this purpose I take two of the plateshereinbefore described as cupped to dif- "ierent templets in such mannerthat these cups should alternate, and I set the edges of each plate (ofthe pair of plates so selected to form one compartment) up to half thedepth of those indentations or cups which determine the space betweenthe pair of plates forming one compartment, and I give each set anexternal flange rectangular to such vertical set, and parallel to theplate, and preferably of three-quarters of an inch in width. The set toone plate is so given that the cups on it are internal to thecompartment, and the set to the other plate is so given that the caps onit are external to the compartment, the cups internal to the compartmentforming the interior supports between the two plates forming thecompartment, and the cups external to the compartment forming theexterior supports in the space existing between one compartment and thenext, which space such cups external to the compartment determine.

1 dip the edges of the plates in a tin bath, so as to tin the copperedge of the plate, and I then lap over the edges and solder all securelytogether with a sweating-joint. After having been tested to about twentypounds pressure per square inch, the compartment is ready for connectionwith any required number of other compartments. The compartments thusprepared are threaded or placed together on a top and bottom pipe orpipes, such pipes being slotted longitudinally so as to communicate withthe interior of the several compartments. Between each compartment andthat next adjoining is threaded on or placed a rubber ring, and externalto such rubber ring is threaded on or placed a spun ring constructed onthin copper-plate, with a semicircular section on its exterior, so thatit is capable of compression when the compartments are set up together,as hereinafter described, and in this manner the rubber is confinedbetween the edges of the holes hereinbefore described, and the copperring external to the rubber; and when the whole is set up, the rubber,by compression between the two, is made to form a perfect joint betweensuch two copper protections.

I place a east-iron or other plate on each side external to any numberof compartments used to form the condenser, and these plates areperforated with holes the same as the compartments, and through theseholes the slotted pipes are passed, having screwed ends to each suchslotted pipe. The joint is again made in the usual way, and the wholeset up by screwing the nuts on the end of the pipes to the requiredpressure. Any number of such compartments can be fixed in a case, inwhich provision is made to receive the projecting ends of the slottedpipes which pass through the case, and are again jointed by the settingup of washers and nuts against the case; and the end of the slottedpipes is made to communicate by any suitable connections with the sourceof the steam or vapor to be condensed. In the condenser-case shown inthe drawings such communications with the ends of the slotted pipes aremade by means of rectangular boxes, which are jointed and bolted on tothe front of the condenser-case, and made to communicate, as theconditions of the application may require, with any other communicationsor conduits to the boiler.

The steam or vapor passes through the compartments, all grease andimpurities being kept out by the application of a gauze-wire purifier atthe entrance. The steam or vapor becomes condensed by the cold water orair which circulates through and fills the condenser-case. The steam orvapor is delivered through the slotted pipes at the top of thecondenser, and in its passage through the condenser meets at oppositesides of the plates the water or air which is supplied to the bottom ofthe condenser-case. The water or air leaves the case at the top andenters a tank, a chimney, or other suitable provision for a continuouscirculation of the condensing medium. The maindentations facingalternately inward and outward, the indentations which extend within thechambers serving to brace the same and the other cups or indentationsserving to separate the chambers from one another.

2. In an apparatus for condensing steam and other vapors, a series ofplates united at the I edges in pairs, and provided with raised annularflanges surrounding the holes in said plates, said annular flanges'ofeach pair of plates interlocking,- substantially as set forth.

3. In an apparatus for condensing steam and other vapors, a series ofplates united to form pairs, each pair inclosing a compartment, and theseveral compartments being separated by elastic packing-rings,substantially as and for the purpose set forth.

4. In an apparatus for condensing steam and other vapors, a wire screenand a shield extending below. or outsideof said screen and serving toprotect the central part of that screen from grease, substantially asset forth.

5. In an apparatus for condensing steam or other vapors, a series ofplates arranged and united at the edges in pairs, as hereiubefore-described, the said plates being formed with indentations or cups, andwith holes having raised edges, and being threaded on slotted pipes, andmade tight at the joints, all substantially as and for the purposeshereinbefore described.

In testimony whereof I affix my signature in the presence of twowitnesses.
